Here are all of Google's employee perks, and how much they cost the company

With free gourmet meals, in-house massages, and dry cleaning on
campus, Google is known for its
extensive list of perks.

Founders Larry Page and Sergey Brin even brought up the myriad
perks in their shareholders' letter when the company went public
in 2004, promising their commitment to providing benefits that
could "save employees considerable time and improve their health
and productivity."

Google wants its people programs to achieve efficiency, promote
community, and spur innovation.

Surprisingly, Google says it doesn't drop as much money as one
might expect on those perks.

"Most people assume Google spends a fortune doing special things
for our employees," Google HR boss Laszlo Bock writes in his
new book "Work Rules!"

"Aside from our cafes and shuttles, we don't," he says.

Here's a chart that shows the cost and benefit of some of
Google's most important perks:

"Most of the programs we use to delight and care for Googlers are
free, or very close to it," Bock writes. "And most would be easy
for almost anyone to duplicate."

If companies want to push themselves toward a culture more
resembling Google's, it's less important to have a ton of money
and more important to try to say yes to employee ideas.
